Patent FR-2694750-A1 (FR)
Title: Combustible component coating on matches - enables combination of the coating and not substrate with formation of coloured flames.
Inventor: BENOIT BALLAND
IPC: C06F3/04
Filed: 1992-06-19
Abstract: The addition of a highly reactive combustible to one of lower activity forms a coating on a wood or cardboard match, facilitating complete combustion of the coating and producing a coloured flame. Pref the match is held at a recessed pt (4) and dipped in a prim both contg a binder, the two combustible components and the cation cpd. The first coating obtd (2) is dried, then the match is dipped in a second bath, to form the 'igniter button' (3), this bath contains the usual ingredients and chlorates or perchlorates of the metal (including borides) to give the colour(s) desired. The soln bath for the prim coating contains an alcohol glycol or acetone as solvent and also hexamethylene tetramine (HMT) cellulose-type binder (without Na) eg hydroxy-propyl cellulose. USE/ADVANTAGE - The coatings contain, in addition to combustibles, various cations (organo-metallic perchlorates or borides) to give different colour flames when the match is struck. The match is pre-treated to render it fire resistant before coating with the combustible/cation mixt, thus the substrate does not ignite which avoids generation of a yellow unburnt carbon flame and does not produce CO and CO2. The match ignites spontaneously over the whole of the coated length and not progressively as in conventional matches. It is safer to handle since the support does not burn.

Title: Fluid treatment system to remove material in suspension or solution - using additives in both fluid and back-washing fluid which neutralise one another, increasing the flow and producing less waste
Inventor: ESPENAN
IPC: B01D65/02
Filed: 1992-11-03
Abstract: Process for treating a fluid containing suspended and/or dissolved material uses a separating membrane. An adsorption and/or filtration additive (the feed additive) is added to the fluid to be treated and a back-washing additive is added to the back-washing fluid. The back-washing additive is chosen such that it can be neutralised by the feed additive and one allows a sufficient contact time after the ejection of the back-washing fluid for the neutralisation to take place. The resulting product is separated into a concentrated solid residual product and a fluid that can be recycled to the start. Appts. comprises a feed (1,2) for the fluid to be treated; a pipe (2a) with a pump (Po) sending the fluid into a separation module (3); a device for injecting the feed additive into the fluid, with eventual recycling of the untreated fluid through a pipe (6) and pump (P1). The device also comprises a back-washing assembly with a pump (P2) lifting the extracted material into a collection drum (5) and a device for adding the back-washing additive (7,P3) characterised in that the back-washing output is sent to a collection drum (9) from which it is removed by a pump (P4) through a pipe (10) via a separation device (11). From this a concentrated residue of solid material exits through a pipe (13) to a drum (14) and a recycled fluid exits through a pipe (14) to the start (1,2). Alternatively, the back-washing output is sent to a contact/separation device (16) where it stays for long enough to produce a concentrated residue of solid material sent to a drum (14) through a pipe (13) and a recycled fluid sent through a pipe (12) to the start (1,2). USE/ADVANTAGE - Fluid is treated to extract material in suspension or in solution (claimed), for example treating water to make it potable. This system increases the flow through the filter membranes by 30-40%, and the back-washing output is separated and partially recycled, thus reducing the amount of waste to be disposed of.

Title: Optical fibre with mechanical and thermal protection
Inventor: JOEL-YVES MARI
IPC: G02B6/44
Filed: 1993-01-21
Abstract: Mechanical and thermal protection of an optical fibre is achieved without significantly increasing the weight and size of the fibre by using a polymer having repeat unit of formula (I) (where X1-X4 are H or halogen and n is at least 5000; pref. X1-X4 are  H and X2-X3 are Cl). The thickness of the coating is about 40 micrometres.The particular polymer known as `Parylene D' can handle temperature up to 300 deg.C and is used in fibroguide engines. The optical fibre has a centre for optical gain and an exterior coating for protection. After depositing the Parylene on the primary coating a crystalline stable dimer similar to the polymer is deposited using sublimation at 250 deg.C for the polymer and 680 deg. C to obtain a monomer is the gas state.

Title: Process for the manufacture of a micromachined device for containing or conveying a fluid
Inventor: FRANS DE ROOIJ NICOLAAS
IPC: A61J3/00
Filed: 1993-05-24
Abstract: This process consists in machining a silicon wafer (4) by selective oxidation and photolithography operations in order to form therein at least one cavity (7, 12) intended to contain or to convey the fluid and in oxidising the wall of the cavity to make it hydrophilic. The device is completed by securing closure plates (1, 5) against its body thus formed. Before the machining operations the surfaces of the wafer (4) are intended to be in contact with the closure plates (1, 5) of a screen-layer which is resistant to these machining operations. Next, after these have been completed, the surfaces of the wafer which are intended to be exposed to the fluid are oxidised to form thereon an oxide layer promoting the wettability of these surfaces. The screen-layer is then removed and the closure plates are secured against the wafer. Application especially to micropumps.

IPC: H04B10/43
Filed: 1994-02-18
Abstract: Le brouilleur de polarisation de ce système reçoit une onde modulée en amplitude (WP). Il comporte un polariseur (34) et un modulateur de phase électro-optique (26) biréfringent. La tension d'une source d'excitation (36) commande ce modulateur.

Title: Fuel and/or ignition control for 4=stroke IC engine
Inventor: HORNEWER JEAN MARC
IPC: F02D41/34
Filed: 1994-09-09
Abstract: An opto-electronic, magnetic or Hall effect sensor (3) detects the passage of identical teeth regularly spaced round a wheel (2) fixed on the crankshaft, passing a continuously pulsed incremental signal to the controller (7). The camshaft carries a disk (4) with a stepped rim, whose radius over one half the circumference exceeds that over the other half. The passage of each step is signalled to controller by another, similar, sensor (5); as the speed is half crankshaft speed, each step. unambiguously represents the position, e.g. TDC, of a particular piston. Thus informed, the controller's central processor, using associated memories and analogue/digital converters, can adjust fuel injection and ignition for optimum performance.
